Compared with the prior art, the combined booster pump station can solve the problems of low comprehensive utilization rate of equipment, and poor buffering performance and peak removal compensating effect of municipal water source in current water supply equipment.

Description

The Combined pressurization pumping plant

Technical field

The utility model relates to the supply equipment technical field, especially a kind of box-type frequency-changing water supply device that has made up water tank and pressure pump group.

Background technology

The supply equipment that is used at present the high residential building supercharging is general to be adopted and overlaps supercharging equipment independently respectively to user's water supply of the different contributing regions of high residential building more, or adopt the series connection of many cover supercharging equipments, the mode of relay pressurizing supplies water to the user of high residential building, and every complete equipment all is provided with water source water receiver and a place or many places buffering water receiver.A plurality of water receivers and the pressure of a plurality of booster water pump groups that such structure is distributed in everywhere whole pumping plant have to a certain degree loss, many complete equipments or a plurality of supercharging equipment also have certain energy consumption between connecting, the pressurization of existing constant pressure frequency conversion control supercharging equipment is subdued to some extent, and the rate of comprehensive utilization of equipment is low; At the water low peak period and municipal ductwork pressure when too high, the water system of this series multistage supercharging equipment relay pressurizing also needs the progressively step-down of multistage water receiver, almost do not have the effect of buffering and elimination surge pressure, thereby be not suitable for significantly variable parameter operation, and system architecture is complicated, equipment manufacturing cost is high, and space availability ratio is low.

Summary of the invention

Problem to be solved in the utility model provides a kind of Combined pressurization pumping plant, and low with the rate of comprehensive utilization of equipment that solves existing supply equipment, space availability ratio is low, to the buffering of municipal water sources and the poor problem of peak compensating action that disappears.

In order to address the above problem, the technical solution of the utility model is: this Combined pressurization pumping plant includes the booster water pump group by frequency-variable controller control, be provided with the gentle flushing tank of airtight water source water tank of water inlet pipe and outlet pipe, the case room that was separated with water tank chamber and pump house in one minute is arranged, the pump house place in described case room has the doorway, and described frequency-variable controller and described booster water pump group place in the described pump house; Described water tank chamber is divided into water tank chamber, water source and buffer tank chamber, described water source water tank places described water source water tank indoor and be provided with the water inlet pipe that a water inlet connects described water source water tank at this chamber locular wall, and described buffer tank places described buffer tank indoor and be provided with the outlet pipe that a delivery port connects described buffer tank at this chamber locular wall; The outlet pipe of described water source water tank is divided into two groups, and wherein one group of outlet pipe connects described buffer tank after connecting described booster water pump group, connects behind another group outlet pipe connection flap valve and states buffer tank; Described water source water tank and described buffer tank top all arrange vacuum suppresser.

In the technique scheme, more specifically scheme can be: the delivery port of described water source water tank is provided with pressure sensor; Be disposed with pressure sensor and flap valve on the outlet pipe of described buffer tank.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, this Combined pressurization pumping plant adopts the integral structure that has made up the gentle flushing tank of water source water tank and pump house, whole pumping plant be can reduce and everywhere a plurality of water receivers and the pressure loss of a plurality of booster water pump groups and the energy consumption between each equipment connection are distributed in, minimizing equipment is made idle work, can utilize more fully the supercharging equipment of frequency conversion system control, improve the comprehensive utilization ratio of equipment;

2, the cisten mechanism of combination, a branch road pressurization between the gentle flushing tank of water source water tank connects, another branch road is by the flap valve connection of not pressurizeing, make water tank gentle flushing tank in water source form a larger steady flow compensator, at the water low peak period and municipal ductwork pressure when too high plays again the effect of eliminating surge pressure and buffering compensation; The flap valve that arranges between them can prevent from again subduing pressure through the aqueous reflux of pressurization branch road pressurization, makes whole pumping plant have enough water-holding quantities to alleviate the peak water;

3, the combination box structure of integral type, floor space is little, and space availability ratio is high; Whole water system adopts closed design, need not any Water-quality treater, and a water inlet and a delivery port only are set, and makes things convenient for installation and maintenance.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing enforcement:

Combined pressurization pumping plant shown in Figure 1 includes the booster water pump group 7 by frequency-variable controller 8 controls, be provided with airtight water source water tank 2 and the buffer tank 9 of water inlet pipe and outlet pipe, the case room 11 that was separated with water tank chamber and pump house in one minute is arranged, this case room 11 has the doorway at this pump house place and is provided with door 12, and frequency-variable controller 8 and booster water pump group 7 place in the described pump house; The water tank chamber is divided into water tank chamber, water source and buffer tank chamber, water source water tank 2 places described water source water tank indoor and be provided with the water inlet pipe 1 that a water inlet connects this water source water tank 2 at this chamber locular wall, buffer tank 9 places described buffer tank indoor and be provided with the outlet pipe 10 that a delivery port connects this buffer tank 9 at this chamber locular wall, a water inlet and a delivery port are set, the user is difficult for when water pipe is installed because of the too much setup error of water pipe head; The delivery port of water source water tank 2 is provided with pressure sensor 4, and the outlet pipe of water source water tank 2 is divided into two groups, and wherein one group of outlet pipe connects buffer tank 9 after connecting booster water pump group 7, and another group outlet pipe connects buffer tank 9 after connecting flap valve 5; Water source water tank 2 and buffer tank 9 tops all arrange vacuum suppresser 3.Be disposed with pressure sensor 4 and flap valve 5 on the outlet pipe 10 of buffer tank 9.

When using the Combined pressurization pumping plant, frequency-variable controller changes to control the pump operation supercharging with assure feed water according to the numerical value of two pressure sensors 4 on the outlet pipe 10 that is arranged on water source water tank 2 and buffer tank 9.At the water supply low peak period and municipal ductwork pressure when too high, booster water pump group 7 shuts down, the numerical value that is arranged on the pressure sensor 4 on the outlet pipe 10 of buffer tank 9 still is higher than preset value, tap water can directly enter buffer tank 9 by water source water tank 2 through flap valve 5 and supply water to the user, reduce simultaneously pressure and make it near preset value, played the effect of buffering and the peak compensation that disappears.
